太陽の影響に関する他の研究

前述の結論は多くの研究によって立証されています：

Erlykin 2009: "We deduce that the maximum recent increase in the mean surface temperature of the Earth which can be ascribed to solar activity is 14% of the observed global warming"「最近の地球表面温度の上昇の１４％が太陽活動の寄与だと推定します。」

Benestad 2009: "Our analysis shows that the most likely contribution from solar forcing a global warming is 7 ± 1% for the 20th century and is negligible for warming since 1980."「２０世紀の太陽強制は7 ± 1%、そして１９８０年からの寄与は取るに足りません。」

Lockwood 2008: "It is shown that the contribution of solar variability to the temperature trend since 1987 is small and downward; the best estimate is ?1.3% and the 2?confidence level sets the uncertainty range of ?0.7 to ?1.9%."「１９８７年からの太陽変動の寄与は微量だが下向きです。最良推定値は1.3％、そして信頼区間は0.7％から1.9％です。」

Lockwood 2008: "The conclusions of our previous paper, that solar forcing has declined over the past 20 years while surface air temperatures have continued to rise, are shown to apply for the full range of potential time constants for the climate response to the variations in the solar forcings."「過去２０年間の地球表面気温は続けて上昇しながら太陽強制は減少しています。この結論は気候応答のどの潜在的な時定数にも適用します。」

Ammann 2007: "Although solar and volcanic effects appear to dominate most of the slow climate variations within the past thousand years, the impacts of greenhouse gases have dominated since the second half of the last century."「太陽と火山活動の影響は過去１０００年の低速の気候変動の大部分を支配していたが、温室効果ガスの影響は２０世紀後半を支配しています。」

Lockwood 2007: "The observed rapid rise in global mean temperatures seen after 1985 cannot be ascribed to solar variability, whichever of the mechanism is invoked and no matter how much the solar variation is amplified."「太陽変動が１９８５年以降の世界平均気温の迅速な上昇の観測に起因しているとは考えられません。どのメカニズムを発動させても、太陽変動を増殖させても同じ結論です。」

Foukal 2006concludes "The variations measured from spacecraft since 1978 are too small to have contributed appreciably to accelerated global warming over the past 30 years."「１９７８年から宇宙船を使って計測された[太陽活動の]変動は、促進した地球温暖化にはっきりと感じとれる寄与をするには小さすぎます。」

Scafetta 2006says "since 1975 global warming has occurred much faster than could be reasonably expected from the sun alone."「１９７５年以降の地球温暖化による気温上昇は太陽の効果だけから期待される上昇よりも遥かに速いです。」

Usoskin 2005conclude "during these last 30 years the solar total irradiance, solar UV irradiance and cosmic ray flux has not shown any significant secular trend, so that at least this most recent warming episode must have another source."「この３０年間、全太陽放射照度、紫外線放射照度、宇宙線量は有意なトレンドを示していません。そのため、最近の地球温暖化は他の根源が寄与しているかと思われます。」

Solanki 2004reconstructs 11,400 years of sunspot numbers using radiocarbon concentrations, finding "solar variability is unlikely to have been the dominant cause of the strong warming during the past three decades". 放射性炭素濃度を使い、過去１１４００年の太陽黒点数の復元を成したSolanki「過去３０年の温暖化に太陽変動が大きな要因である事は疑わしいです。」

Haigh 2003says "Observational data suggest that the Sun has influenced temperatures on decadal, centennial and millennial time-scales, but radiative forcing considerations and the results of energy-balance models and general circulation models suggest that the warming during the latter part of the 20th century cannot be ascribed entirely to solar effects."「観測データによれば、太陽は１０年、１００年、１０００年スケールで気候に影響してます。ですが放射強制力を考慮し、エネルギーバランスモデルや大気循環モデルの結果から推論すれば、２０世紀後半の温暖化の大部分は太陽によるものと示唆しがたいです。」

Stott 2003increased climate model sensitivity to solar forcing and still found "most warming over the last 50 yr is likely to have been caused by increases in greenhouse gases." Stottは太陽強制に対する気候モデルの感度を増加しても同じ結論に達した「過去５０年の温暖化は温室効果ガスが一番の原因と思われます。」

Solanki 2003concludes "the Sun has contributed less than 30% of the global warming since 1970".「太陽の寄与は１９７０以来の地球温暖化の３０％以下です。」

Lean 1999concludes "it is unlikely that Sun–climate relationships can account for much of the warming since 1970".「１９７０以来の温暖化に太陽-気候の関係が大きな要因である確率は小さいです。」

Waple 1999finds "little evidence to suggest that changes in irradiance are having a large impact on the current warming trend."「放射照度が現在の温暖化トレンドに大きな効果を与えてるという根拠は乏しいです。」
